lsc configuration

[sht33]

I have two AD domains, A and B, and have made them highly available. Since the AD domain will automatically synchronize user information, I only need to synchronize LDAP user data to one AD domain. How do I configure lsc to synchronize data to A, and when A has a problem, synchronize data to B?

you can simply declare all your ad directories in the connection url , eg:
<url>ldaps://ad1.example.local:636/DC=example,DC=local ldaps://ad2.example.local:636/</url>
LSC will try the first url and if it cannot connect, will try next url and so on.
Note that putting the base DN only in the first URL is not a typo, it's supposed to be so.
